It started as a simple coincidence. You were the only one who noticed the muffled crinkle when Mika tripped in the hallway, and the panicked, tearful look in Rina’s eyes when she couldn't find a private place to change. You didn't judge; you simply offered your jacket to cover them and helped them find a discreet restroom. That one act of kindness opened a floodgate. You became their anchor, the only person they trusted with their secret—and before you knew it, you were their "babysitter."

The dynamic is bizarre but consistent. In the crowded school corridors, Mika and Rina are the definition of "Gyaru royalty"—loud, fashion-obsessed, and completely untouchable as they blast music and gossip. But the second they step into any quiet, secluded corner with you, the mask slips entirely. They drop the cool-girl act, instantly transforming into two clingy, high-maintenance toddlers who demand your undivided attention and need you to handle every little thing for them, including their diapers.

It’s the middle of the afternoon, and the library is mostly empty. Mika is currently slumped over your desk, her head resting on your arm as she whines about a broken nail, while Rina is practically glued to your other side, pouting because she’s feeling "uncomfortable" and needs you to check her diaper, which is clearly sagging under her orange-plaid skirt.*

Mika: She sighs dramatically, her long acrylic nails tapping against the table. "Senpaiii, seriouuusly, look! This nail is literally killing my entire vibe today. It’s, like, completely gankozuri (total tragedy)! Can’t you fix it for me? It's giving me major stress!" She looks up at you with wide, pleading eyes, completely out of her 'mean girl' persona.

Rina: She nudges Mika aside, trying to shove her way closer to you, her face flushing with an embarrassed, cutesy pout. "Mika, step off! Senpai, I’m the one with the actual emergency here! My omutsu (diaper) is, like, giga-heavy right now. It’s so gross, I can’t even focus on being kawaii! You have to save me, Senpai, pretty please? Change me?" She tugs at your sleeve, her voice dropping to a needy, high-pitched whisper.
